When planning the cement pipeline system, the slope of the cement pipeline above the overflow water level should be minimized to reduce the length of the ponding pipe section and the amount of ponding in the drainage system. The slope of the cement pipeline below the overflow water level should not be too small, and it should be ensured that the water flow has a certain scouring strength on the pipeline when the pipeline is evacuated. This method is applicable to the control point of the cement pipeline which is close to the access point of the municipal cement pipe network. If one method is adopted, the cement pipeline in the community cannot be connected to the municipal pipe network, and the residential community or factory area with small scale is also applicable to the rainwater drainage system. When used in the rainwater drainage system, rainwater is discharged through overflow wells. The rainwater pump is only opened after each rain and when the pipeline needs to be dredged and maintained, so as to remove the accumulated water in the pipeline.

1. Before putting the cement pipe into use, check whether the cement pipe is intact. If there are cracks, repair them in time. If they cannot be repaired, replace them. Do not use damaged or inferior cement pipes, which will affect the safety of the project. 2. The workers of cement pipe laying must have professional experience, the relevant departments should do a good job in supervision, and each procedure should be well controlled, otherwise the unqualified foundation in the early stage will lead to more problems in the later construction, and the problem should not be buried underground, because maintenance will consume a lot of human and financial resources. 3. When laying pipelines, the established construction scheme shall be strictly followed, and do not make decisions or cut corners, otherwise the project quality will not be guaranteed. 4. After the cement pipe is laid, the special quality inspection department shall further review it to ensure the project quality.

Cement pipes can be used in many fields, such as rainwater drainage, sewage drainage, industrial wastewater drainage and community drainage. As well as the buried pipelines of highways, or for protecting cables, optical cables, etc. Cement pipes have the following characteristics: 1. Generally speaking, they have rigidity, flexibility and excellent mechanical properties. And it has strong compressive properties. 2. The chemical property is stable, generally corrosion resistant, but non-toxic, and it is an excellent environmental protection pipe. 3. For the connection, as long as the flexible rubber ring is used, the street seal can work well. Long term operation. High quality, no leakage 4. The inner wall of the pipeline is flat and yellow, and the fluid friction is relatively small. If used on the ground, the service life will exceed 20 years.

The shape of square pile is easier to develop a non welded quick connector, which can truly achieve all-weather construction, and construction is faster, which can avoid cracking of welded pile head in high groundwater level. 1) Positioning, centering and leveling of the pile driver. After the mixing pile position is placed, move the mixing pile driver to the designated pile position, centering and leveling (leveling with a level). 2) Adjust the verticality of the guide frame, and use a theodolite or plumb bob to control the verticality of the guide frame in both directions. According to the design and specification requirements, the verticality is less than 1.0% of the pile length. 3) The slurry is premixed in advance. While the deep mixer is premixing and sinking, the cement slurry is mixed in the background and put into the aggregate hopper before grouting. The cement grade 425 # ordinary silicate cement is used to mix the slurry, the water cement ratio is controlled in the range of 0.45~0.50, and the cement consumption per meter of deep mixing pile is not less than 50Kg according to the design requirements.

Principle of intercepting tank method: in the sewage drainage system, the intercepting tank is used to block the substances that are easy to deposit in the sewage, so as to prevent pipe blockage caused by the reduction of pipe slope and flow rate, so as to reduce the value of smaller planned flow rate and smaller planned slope of the cement pipe as appropriate, so as to reduce the buried depth of the cement pipe. During detailed planning, ordinary septic tank can be used as interception tank. Since the intercepting tank mainly blocks the easy sediment in the sewage and does not need anaerobic fermentation to purify the sewage, the volume of the sewage part can be taken as 1/3 of the normal septic tank, while the volume of the whole intercepting tank is about 1/2 of the normal septic tank.
